特長
- DIF cycle-to-cycle jitter < 50ps
- DIF output-to-output skew < 50ps
- DIF phase jitter is PCIe Gen 1-2-3 compliant
- Very-low additive phase jitter in bypass mode
- Integrated terminations provide 100Ω differential Zo reduced component count and board space
- 1.8V operation; minimal power consumption
- Outputs can optionally be supplied from any voltage between 1.05V and 1.8V; maximum power savings
- OE# pins; support DIF power management
- HCSL-compatible differential input; can be driven by common clock sources
- LP-HCSL differential clock outputs; reduced power and board space
- Programmable slew rate for each output; allows tuning for various line lengths
- Programmable output amplitude; allows tuning for various application environments
- Pin/Software selectable PLL bandwidth and PLL Bypass; minimize phase jitter for each application
- Outputs are blocked until PLL is locked; clean system start-up
- Software selectable 50MHz or 125MHz PLL operation; useful for Ethernet applications
- Configuration can be accomplished with strapping pins; SMBus interface is not required for device control
- 3.3V tolerant SMBus interface works with legacy controllers
- Space saving 48-pin 6mm x 6mm VFQFPN; minimal board space
- Selectable SMBus addresses; multiple devices can easily share an SMBus segment
説明
The 6P61033 is an 8-output very-low power buffer for 100MHz PCIe Gen 1, Gen 2, and Gen 3 applications with integrated output terminations providing Zo = 100Ω. The device has eight output enables for clock management and three selectable SMBus addresses.
